操作符
获取,即a。因此以C语言的函数传递中具备两种方式传递参数,一种是传址,一种传值。比如voidf1(intv){;}//函数f1v
我的方案是将相关dll的放入vb的资源文件中,生成exe,在exe执行时先将dll释放到exe目录(或path所在目录),这样就只有1个exe就可以了
加以一个panel用来显示应用程序的,就是放你那个easycap的,代码如下
Declare Function SetParent Lib "user32" Alias "SetParent" (ByVal hWndChild As IntPtr, ByVal hWndNewParent As IntPtr) As Integer
Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Int32, ByVal wMsg As Int32, ByVal wParam As Int32, ByVal lParam As Int32) As Int32
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Int32, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Int32) As Int32
Private Const WM_SYSCOMMAND As Int32 = H112
Private Const SC_MAXIMIZE As Int32 = HF030
Private Const SC_MINIMIZE As Int32 = HF020
Private Const SC_RESTORE As Int32 = HF120
Public Const SW_HIDE = 0
Public Const SW_SHOW = 5
Private Declare Function ShowWindow Lib "user32.dll" (ByVal hwnd As Int32, ByVal nCmdShow As Int32) As Int32
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ShellExecute(Me.Panel1.Handle, "open", "c:\windows\system32\cmd.exe", Nothing, ".", SW_HIDE)
System.Threading.Thread.Sleep(50)
Dim h As IntPtr = FindWindow(Nothing, "c:\windows\system32\cmd.exe")
ShowWindow(h, SW_HIDE)
SetParent(h, Me.Panel1.Handle) '嵌到panel1内
SendMessage(h, WM_SYSCOMMAND, SC_MAXIMIZE, 0)
End Sub
把其中的c:\windows\system32\cmd.exe换成你要嵌入的应用程序
